Mr Bevan went on: “There's been a great deal of speculation about this case, including the names of suspects potentially linked to this murder.

“We don't have a prime suspect and we don't have any conclusive evidence to suggest Melanie's death is linked to any other murders or sexual offences committed in our force area, or elsewhere in the country.

“There are, however, numerous people of interest in this investigation and we're looking into whether they have any potential link to this horrific crime.
